yThe Schedule referred to in these Letters Patent and malring part ofthe saine To all 'whom 'it 'may concern y Be itv known that I, O. HOLLER, of Cincinnati, in the county of Hamilton, and State of- Ohio, have invented a new and useful Improvement` in Ice-Spurs, for Boots and Shoes, of which the following is a full,

companying drawings, makingpart of this lspecifica- My invention consists in a s tirrup-shaped frame of metal, armed with spurs, and provided with prominent and eccentrically-pivoted knife-edges, which are designed to enter the `heel of the boot or shoe, when the metallic frame is adjusted upon it.

The object of thisV device is to prevent slipping, where the pedestrianY passes over icy surfaces.

Figure l is a perspective view of my improved icespur, as it appears before being applied to the heel of 4the boot.

4Figure 2 is 'a plan of the rear section of the icef spur, ,the .eccentrically-pivoted knife-edges projecting within the frame of the ice-spur.

Figure 3 is a longitudinal section of the same, and asection of` oneof the'spurs. 4

A is the frame ct the ice-spur, constructed of metal, and having the shape of a stirrup.

A is the bridge-piece secured toA the ends of the curved frame A; is concave on the upper face', and is, provided with a cushion of leather, a,or other suitable material, riveted-'to bridge A.- X 4 i Aangle-point of union ofthe frame A and the'bridge Ai lu length they 4Steel points c project from the-extreme ends of' the bosses b, to which they are securely attached, being either tapped in or, whichis more economical, and to be preferred, bedded in the metal when cast.I

d are.knifeedges, projecting rearward from the bridgeAQof which they are apart.

The two eccentric knife-edges B, attached to the handle B', are pivoted to the frarneA, directly opposite the centre of the bridge A.

c isa recess inthe side of the frame A, adapted to l receivethe end f of the handle B', when the knifeedges are caused to enter the heel, having been rotated through about the one-fourth of .a complete circle.

When it is desired to adjust the ice-spur to the heel,

of the heel, and the ice-spur is secured tolthe boot, as

exhibited in the section, iig. 3.

For equestrians I design substituting a pointed setscrew in the centre of the rear of the fraineA, in place of the eccentrically-placedknife-edges. The set-screw will be provided with an ordinary spur, which will serve the purpose of securing the set=screw in the The ice-spur herein described is both novel and sim# ple in construction.

What I claim as new, and desire 'to secure by Let-` ters Patent, isy 4'.l-he frame A, the bridge A', provided with a series ,of knife-edges, the bosses b, armed with steel-points,

the cushion a, and eccentric knife-edges B, or their equivalent, -when the sameare constructed and arranged substantially as and for the purpose specified.
